(Method for Forming small recess b 1 Oyopi small projections b 2)

Small recess b 1 and the small protruding portions b 2 provided on the adhesive layer B, by using a release sheet over preparative C was perforated, when the release sheet C and the pressure-sensitive adhesive layer B are laminated (indirect coating for the time the adhesive coating to the release sheet C), the release sheet ridges c 1 of C to form a corresponding small recess b 1 bite into the basic flat surface of the adhesive layer B. At the same time the release sheet adhesive than the base flat surface of the adhesive layer B to perforate structure c 2 of C to form a small protrusion b 2 which corresponds to the inflow. These small recess b 1 are those corresponding to the ridges c 1, the small protrusions b 2 are those corresponding to the perforate structure c 2.

In addition, in the case of direct coating to provide a pressure-sensitive adhesive layer B on the sheet substrate A directly, ridges c 1 of the release sheet C when stacking a peeling sheet Ichito C basic flat surface of the adhesive layer B simultaneously makes a corresponding small recess b 1 crowded had food, extruded adhesive around the Okubo body portion bl, it is formed as dikes as small projections b 2 in. In this case, arise small recess b 1 is something that corresponds to the raised portion c 1, it does not necessarily correspond to the small protrusion b 2 and the perforated structure c 2.

Recessed depth of the small recess b 1 is preferably thickness range from basic flat surface 1 mu m to pressure-sensitive adhesive layer B of the adhesive layer B, 3 μ πι~ adhesive layer from the base flat surface and more preferably a thickness range of the B. In less than 1 m depth of the small recess b 1, Okubo only part b 1 also tends to adhere to the adherend, gas generated from the fine air or adherends remaining results to accumulate unevenly to generate a blister significantly impair undesirably the appearance.

Protruding height of the small projections b 2 is preferably in the range from the basic flat surface of 1 / zm~l 5 0 m of the adhesive layer B, ranging from the basic flat surface of 3 μ m~ 1 0 0 m more preferably. The height of less than 1 m of the small projections b 2, when adhering the pressure-sensitive adhesive-processed sheet to the adherend, a gap communicating to the outside between the adhesive layer B and the adherend is deflated for small is poor becomes, resulting in increased to generate uneven swelling significantly impair undesirably the appearance. The 1 if 5 0 larger than the mu m can not contact the base flat surface be crimped strongly after pasted on an adherend and the adherend surface, disadvantageous strong adhesion when determined Mel unfavorable work in.

Small recess b 1 of the recess depth, protruding height of the small projections b 2 adjusts the adhesive processing sheet after processing to a temperature below the glass transition point of the adhesive to cross with Miku port storm switching Operation out, after ion etching and gold deposited in a commercial ion coater, a scanning electron microscope (trade name: S- 3 0 0 0 N, (Ltd.) manufactured by Hitachi high-Technologies) at was calculated from the cross-sectional configuration.

The shape of the small recess b 1 is than also transferring the essentially release sheet C-shaped ridges c 1 of, but are not particularly limited, flat line to the basic flat surface of the adhesive layer B a cross-sectional shape in the plane is circular, elliptical, toroidal, crescent, n polygon (n is a natural number of 3 or more) can at least one selected preferably shape selected from the group consisting of, in particular toroidal, crescent is preferably at least one or more shapes selected from any of the forms.

In punching the shapes to the release sheet C is a technique of the present invention, a suitable shape which can be selected, in particular toroidal, crescent preferred in that can be molded in inexpensive treatment process.

Similarly, the cross-sectional shape of the basic small protrusion b 2 in a plane parallel to the base flat surface circular, elliptical, toroidal, crescent, gourd-shaped, selected from the group consisting of 11 square (n is a natural number of 3 or more) at least one can be preferably selected shape was, Donna Tsu-shaped, basic crescent, more preferably at least one shape selected from the group consisting of a gourd-shaped, small recess b 1 along the contour of the flat plane base portion, and particularly preferably a shape formed adjacent its outer periphery.

By providing the shape described above, hardly even noticeable as produced is fine blisters, it will not be seriously impaired appearance.

The techniques of the present invention is the small protrusion b 2 and the small recess b 1 are each independently, it may also be exist apart, small recess b small protrusion b 2 adjacent to one formation If that is the minute air remaining between the adhesive layer B and the adherend or gas generated from the adherend, concentrated in a small recess b 1 adjacent to the small protrusion b 2 It is to incorporated, non-uniform swelling can be effectively suppressed.

Small recess b 1 are numerous on the base flat surface, they were separated from each other, preferable be interspersed. If the small recess b 1 exists densely decreases the rate which accounts for basic flat surface, the adhesive force of the adhesive base sheet is reduced by portion thereof. If it is sparse which may blisters not completely can capture fine air or gas between the adhesive layer B and the adherend occurs.

Small recess bl is preferably distributed in 1 0-1 0, 0 0 0 / cm 2 of frequency, 1 5-5, that are distributed at a frequency of 0 0 0 / cm 2 still more preferably Les,.

Small recess b 1 of the pressure-sensitive adhesive layer B, since it is shall be shaped to correspond to the raised portion c 1 of the release sheet C, the raised portion c 1 of the release sheet C is similar to the small recess b 1 at a frequency, in which it distributed similarly.

If the distribution frequency of the small recess b 1 is less than 1 0 cm 2 is not preferable to lower the swelling prevention effect. 1 0, 0 0 0 / cm 2 is not preferable not obtained adhesive strength to required if more than.

Small recess b 1 is particularly preferably evenly distributed on the base flat surface in terms of the blister prevention.

Similarly the small protrusion b 2 are numerous on the base flat surface, they were separated from each other, preferred it that Mashimashi dispersed. If the small projections b 2 are densely present is reduced the contact area between the adherend, sufficient bonding strength can be obtained even by crimping strongly. When the case that has become sparse to adhering the pressure-sensitive adhesive-processed sheet to the adherend, a gap communicating to the outside between the adhesive layer B and the adherend is uninflated deteriorates to become small, resulting in large which may occur non-uniform swelling.

Small protrusions b 2 are preferably distributed in 1 0-1 0, 0 0 0 / cm 2 of frequency, 1 5-5, are distributed at a frequency of 0 0 0 / cm 2 it is not more preferable.

Release sheet perforated structure c 2 of C is at substantially the same frequency as the small protrusion b 2 of the pressure-sensitive adhesive layer B, and which was distributed similarly. Significantly impair undesirably greatly uneven blister occurs appearance when the distribution frequency of the small projections b 2 is less than 1 0 / cm 2. 1 0, 0 0 0 / cm 2 unfavorable not adhesive strength is obtained for required if is exceeded.

Distribution frequency on the base flat surface of the small protrusion b 2 may be a uniform one as long as it is within the above range, it may be non-uniform. If uniform sheet over the entire surface can have a uniform adhesion, workability is improved. If uneven partially adhesion can create weak meta labels, etc., it can be applied to a coupon labeled. The size of the small protrusion b 2, the maximum width of the base in the basic flat surface 1 to 1, is preferably 5 0 0 / im, 3~1, and more preferably 0 0 0 xm. If the maximum width of the small projections b 2 is less than 1 m, the adhesive layer B and fine blisters not completely be captured air or gas is not na preferred for thereby generating between the adherends. If the width of the small projections b 2 is greater than 1, 5 0 0 μ ιη is to decrease the area ratio, which accounts for a basic flat surface, the adhesive strength to request can not be obtained undesirably.

The sheet one preparative substrate Α adhesive processing sheet of the present invention can be subjected to decoration in various printing methods. As printing method, an electrophotographic method, melt thermal transfer method, a sublimation thermal transfer method, rewritable marking, and use of printers such as an inkjet method, of course, letterpress, gravure printing, flexographic printing, solvent-offset printing, UV curable offset printing, various printing methods such as screen printing leave in applications.
